"During Dark Twisted, we realized that no one's email was secure, whether it was Gmail or .mac or iDisk," Anthony Kilhofer, one of the engineers on Watch the Throne, told Billboard.

3.He also stopped working in regular recording studios, choosing to instead set up small studios in hotel rooms and other locations where he could keep out anyone besides trusted inner circle collaborators.

6.Many albums are leaked around the time CDs are manufactured or shipped, but West made sure Watch the Throne was sent to a secured CD plant after its digital release.

7.Unlike Watch the Throne, Yeezus will be out on CD the same day it's being released digitally. There's a good chance that someone could leak it in this stage, but big box chains make it difficult for this to happen.
